FAQ
What is DGK-PE DDL20 mainly used for?
DGK-PE DDL20 is mainly used for zinc-bromine flow battery bipolar plates, extruded sheets and welded plate assemblies that need PE-based chemical resistance and carbon-plastic electrical performance.
Why use PE for zinc-bromine flow battery bipolar plates?
PE offers good corrosion resistance in zinc-bromine battery environments and can be processed into weldable sheet structures. DGK-PE DDL20 is designed to keep that processability while providing useful mechanical strength for plate handling and assembly.
What processing route is recommended?
The grade is intended for extrusion forming. Sheet thickness, cooling rate, die setting and welding process should be validated together because they affect plate flatness, weld quality and final stack assembly.
What mechanical values should engineers reference first?
Typical project values are density 1.4 g/cm³, tensile strength >25 MPa and flexural strength >25 MPa. Final design should still verify the actual plate thickness, welding design and electrolyte exposure condition.
